Abstract

One of the phenomena which cannot be avoided in a hip prosthesis due to sliding contact as a product of human activity is a wear on the surface of contact interaction. The wear in a bipolar model of the hip prosthesis (the bipolar model) is more complicated than an unipolar model of the hip prosthesis (the unipolar model). There are two contact interactions in the bipolar model, while the unipolar model has only one contact interaction. Wear on the liner and cup surfaces of the bipolar model itself can be early estimated by investigation the contact stresses due to their contact interactions. The contact stress on the liner surface of the unipolar model can be estimated using an analytical method. However, the estimation of contact stress on the liner and cup surface of the bipolar model using analytical method still need to consider. The purpose of this paper is to study the contact stresses on the liner and cup surfaces of the bipolar model using the finite element simulation. There are three models of hip prostheses which are simulated in this research, i.e. the unipolar model, bipolar model and big head unipolar model. The results showed that the maximum contact stress on the liner surface of the bipolar model is higher than the unipolar model. The maximum contact stress on the cup surface of the bipolar model is lower than the big head unipolar model. Based on these results, it can be concluded that the contact stress on the liner and cup surfaces of the bipolar model cannot be estimated using the analytical method.
